<p>在此我们使用三方登录需要定义一个获取三方url的类，还要定义一个回调的类，可以使用工厂来获取我们需要使用的不同类</p>
<h3 id="三方登录"><a href="#三方登录" class="headerlink" title="三方登录"></a>三方登录</h3><ul>
<li>OAuth(开放授权)是一个开放标准，允许用户让第三方应用访问该用户在某一网站上存储的私密的资源（如照片，视频，联系人列表），而无需将用户名密码提供给第三方应用。</li>
<li>OAuth允许用户提供一个令牌，而不是用户名和密码来访问他们存放在特定服务提供者的数据。每一个令牌授权一个特定的网站（例如，视频剪辑网站），OAuth让用户可以授权第三方网站访问他们存储在另外服务提供的某些特定信息，而非所有内容。</li>
</ul>
<h5 id="登录流程"><a href="#登录流程" class="headerlink" title="登录流程"></a>登录流程</h5><p>比如钉钉登录来说，首先设定好用户钉钉扫码的url，然后用户点击钉钉登录时会访问这个url，等登录完成后会回调一个页面，并携带一个code参数，再使用这个凑得既可以获取到用户的信息</p>
<h5 id="为什么使用三方登录"><a href="#为什么使用三方登录" class="headerlink" title="为什么使用三方登录"></a>为什么使用三方登录</h5><p>服务希望用户注册，而用户懒得填写注册时的各种信息同时也为了保证用户的唯一性，密码格式限制，而像一些常用软件基本每个人都会安装的，肯定会在其中一个中注册过，首先解决了注册用户在应用中的唯一性</p>
<ul>
<li>并且三方登录是<code>双因子登录</code>，要只输入账号密码安全性要更高。好处多多的</li>
</ul>
<blockquote>
<p>首先在app应用下新建一个<code>factory.py</code>文件</p>
